I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This might sound silly, but is the time zone correct?
See if upgrading your BIOS will help the situation

it's a vmware guest

the time zone is correct
1. Maybe you guest windows virtual machine is joined to the same domain as your host machine and syncing to the server who has the PDC emulator role.

2. Configuring VMware Tools in a Windows Virtual Machine

3. VMware Workstation guest OS (Windows) resets date/time to host on restart
The .VMX didn't contain any of these parameters except tool.syncTime = "False". Just try to edit/add these parameters to the .VMX file
tools.syncTime = 0
time.synchronize.continue = 0
time.synchronize.restore = 0
time.synchronize.resume.disk = 0
time.synchronize.shrink = 0 = 0
After setting up a desired time in guest OS and after reboot, it came up properly with the desired time.
